ENCRYPTED MULTI KEYWORD SEARCHING FOR SECURED CLOUD STORAGE

Cloud computing is considered to be one of the on demand information technology which combines existing and new techniques from search areas such as service oriented and Virtualization. Cloud computing provides users and various enterprises to store and process their data either privately or by third party data centers. Due to its high performance, cheap cost and high computing power cloud computing has been reported to be one of the highly demanded services. Data Owner outsources their data to public cloud for greater flexibilities and economic savings. But due to existing of single keyword or Boolean keyword search it leads to give undifferentiated results because of which encryption on cloud data search system has become a very challenging task. Some of the issues are less security, missing data integrity. So we proposed a system which defines and solves the problem of multi-keyword ranked search over encrypted cloud data by eliminating unnecessary network traffic and in this we send only the most relevant data to cloud server. Data Owner uploads their data along with the Index file and the search result is ranked by the cloud server. So the proposed system provides high security, preserving data integrity and confidentiality.
